Specification of Letters Patent.

Patented Sept. 10, 1907.

Application filed January 30, 1906. Serial No. 298,646.

Toull whom it may concern:

Be it known that 1', Enwrn E. BARNEY, a citizen of the United States,'and a resident of Syracuse, in the county of-Onondaga and State of New York, have invented certain new and useful Improvements in Type-Writing Machines, of which the following is a specification.

My invention relatesmore especially to ribbon ,vibrators, guides orcarriers of typewriting machines, .and its main object is to provide means whereby the ribbon may run'or be fed true and even, and without creasing, folding or doubling. To the above and other ends, the invention resides in the features of construction and combinations and particularly pointed out in the claims.

In the accompanying drawings, Figure 1 is a fragmentary, vertical, sectional view of the upper part ofatypewriting machine showing my invention. Fig.

2 is a fragmentary front elevation of the upper part I of the machine on a smaller scale than that of Fig. 1.

' being omitted for the sake of clearness.

V 'A guide bracket 3 is secured by headed screws 4 to lugs 5 depending from the top plate, said guide bracket being provided with two vertically disposed parallel arms 6, the outer edges of which are provided with longitudinal grooves or guide ways 6 (Fig. 5). An ink ribbon? is wound on and has its ends secured to ribbon spools 8 horizontally disposed above the top plate forward of the platen and below the printing point on the latter. Said'spools are surrounded by rims or bands 9 secured to the top plate by screws 10 and provided with upwardly and rearwardly inclined 'slots 11 through which the ribbon 7 passes. Each ribbon spool is supported at the upper end of a rotary shaft 12, said shaft being journaled in fixed bearings 13 and being connected with any suitable construction of mechanism for turning the spools and feeding the ribbon back and forth upon and between them. The central portion of that part of the ribbon which extends across the machine between the spools in front of the platen is preferably maintained normally below the printing point and is, during printing operation, moved to cover the printing point and is thereafter moved back to again uncover the printing point.

arrangements of parts hereinafter fully described and This to-and-iro or vibratory movement of the ribbon is controlled by a vibrator, guide or carrier which is preferably made of sheet metal and preferably comprises a stem 14, a cross head 15 at the top of the stem and a pair of slides 16 carried at the ends of the crosshead. The two laterally extending arms composing the crosshead are folded back on themselves at 17 and the slides 16 are thereby turned towards each other so that they may engage the slotted longitudinal guide ways 6" in the vertical arms 6 of the guide bracket 6 5 3. The lower portions of the slides 16 extend below and the upper portions of said slides extend above the cross head. The upper portions of the slides 16 are provided with, forwardly extending stiffening flanges or ribs '18 which are adapted to give rigidity to the slides, said flanges being at right angles to the slides proper. Projecting forwardly and laterally from the lower ends of the flanges 18 are extensions or lugs ll), the ends of which are curled or folded, as indicated at 20, to receive the lower ends of angularly disposed fingers or guide wires 21 and hold them socurely in position. The guide wires extend upwardly and towards the rear of the machine, lying in a plane transverse of the machine, which plane is at an angle to the general plane of the vibrator. In Fig. 4 the transverse plane of the wires 21 is indicated by the broken line y, and the general plane of the vibrator by the broken line 9:. The upper ends of the guide wires 2] are bent horizontally and forwardly, forming hook-like portions 227 It will be understood that the guide wires or their equivalents may be connected with the body of the vibrator in any other suitable way which will permit them to be disposed angularly' substantially as shown.

The upper outer portions of th e slidcs l6 cooperate 0 with the guide wires 21 to form ribboii guiding slots 23. The ribbon passes from oneribbon spool 8 through the slot 11 in the spool case, and thence rearwardly, inwardly and upwardly to the ribbon carrier, first passing in front of and over the finger or guidewire 2]. which forms the outer wall of the slot 23, and then behind the associate slide [6 which forms the inner wall of the slot, the inner edge of said wall being a right-angle corner 24 formed by the slide 16 and the associate stiffening flange l8. Thence theribbon-passcs across the ribbon carrier behind the other slide 16, over its right-angle corner 24, through the slot 23, over and in front of the associate fingeror guido wire 21 to the other ribbon spool through the slot ll in the associate spool, band or case 9. The pathof the ribbon through the carrier is shown clcarlyin Fig. 6. The lower end of the stem J4 of the carrier is bifurcated to form arms 14", secured to the ends of which is a cross pin Engaging the cross pin 25 between the arms 14 is the slotted forward end ofan operating lever 20 fulm'unied at 27 in a lug 2S,dcpending from the top plate. The rear arm of the operating lever 26 is connected by a link 29 with a suitable construction of actuating mechanism which is adapted, at printing operation, to move the ribbon carrier or vibrator from normal position to printing position and thereafter to'permit the return of said ribbon carrier to normal position. I k

Preferably threading the ribbon in the ribbon carrier a loop of that portion of the ribbon between the spools is passed under the hooks 22 and down'through the slots 23, said hooks thereafter serving to prevent the accidental detachment of said ribbon from the ribbon ribbon guiding slots are not parallel, the inner walls of said slots lying in a vertical transverse plane ac which is also the general'plane of the vibrator and the outer walls of said slots lying in a transverse plane y which is at an angle with the plane as. The walls of the guide slot are parallel viewed from the front, but lie in transverse planes which intersect each other,, said transverse planes being, of course, parallel to a common line such as the longitudinal axis of the platen. The lugs 19 form the bottoms of the ribbon guiding slots and the guide wires 21 composing the outer walls of said slots being forward of the plane 05 and extend towards it, being quite close to said plane at their upper ends. In

' other words, the distance between the working faces or edges of the walls of each slot at their lower ends is greater than 'the distance between the working faces or edges of the walls of each slot at their upper ends.

This will be understood clearly from a consideration of 7 face of the carrier and moves longitudinally past the printing point, in this case in a vertical plane, While the direction of its movement towards and away from the carrier is oblique to said vertical plane, because the spools at either side of the carrier are forward of and below the horizontal plane of the printing line, and in the arrangement of the parts illustrated in the drawings are also below the guide slots in the ribbon carrier. These guide slots, viewed from the front of the machine, are vertical and parallel and ii the walls of said slots were also in the same or parallel transverse planes, as in constructions prior to my present invention, the top edge of the ribbon would become taut while the other edge would he loose and slack. In such prior constructions this loss of uniformity in the tension of different portions of the width of the ribbon has proved objectionable, owing to the tendency of the slack edge of the ribbon to become wrinkled or folded, thereby spoiling the .ribbon and prevent mg; clear type impressions from being made from it. With my improved construction, however, owing to the angularly disposed outer walls of the slots in the ribbon carrier, the slack at the lower edge of the ribbon is taken up and the longitudinal tension is rendered substantially even throughout the width of the ribbon, so that one edge is neither tighter nor looser than the other, and wrinkling or folding is prevented. The angular disposition of the outer walls of the guide slots may be increased or decreased according to the obliquity of the path. taken by the ribhon-in passing from spool to spool through the carrier. it will be seen, therefore, that the ribbon is conducted through the ribbon carrier past the printing point in a smooth or flat condition, and this whether or not the ribbon carrier constantly covers said printing point. If the carrier is adapted to be moved to and from the printing point during printing operations, the resist-- ance on thepart of the ribbon to the lifting action of the ribbon carrier or vibrator in prior constructions having vertical slots has generally taken the form of a longitudinal tension along the upper edge of the ribbon, due to .the natural downward drag of said ribbon, while the lower edge thereof has been correspondingly slack, thereby increasing the tendency to crease or wrinkle found in the above described prior constructions of ribbon carriers which are adapted to maintain the ribbon constantly at the printing point. With either style of ribbon carrier, that is, with a ribbon carrier which is fixed or with one which is vibratory, my'present invention is adapted to do away with the objectionable lack of uniformity in-the tension and the consequent wrinkling of the ribbon. By my invention means are provided whereby the ribbon will run-true without creasing or folding not only in the lower normal position of the vibratory carrier but also in the upper or printing position of saidcarrier as has been determined in practice. When a ribbon is wound swiftly from one spool to another by turning either the spools by hand or by operating the usual hand crank the ribbon is very apt to crease or fold and double in the use of prior constructions. Butwith the improved construction herein set forth the objectionable creasing and folding in rapid operation does not occur.

The guide wires 21, composing the outer walls of the ribbon guiding slots, may be so disposed that their lower portions may project far enough forward from the general plane of the carrier to take up as much of the slack at the bottom edge of the ribbon due to the downward inclination of the latter towards the ribbon spool after leaving the ribbon carrier, as may-be desired. Stated in another way, this is equivalent to saying that by my arrangement the ribbon may be directed from the slots in the ribbon carrier downwardly and laterally towards the slots in the spool cases. It will be seen from an inspectionol Fig. (i that because of the angular disposition of the fingers or guide wires 21, the ribbon as it passes over them towards the spools will lie in intained'in'a single inclined plane extending upwardly "and towards the rear oi the machine, lhcrebeing no twist in the ribbon between the spool case and the vibrator. I v

So far as I am aware it is novel to provide a ribbon carrier having ribbon guiding slots in which the operative walls of each slot are further apart at oneend than at the other and also novel to provide a slotted carrier in which one wall of each slot is angularly disposed to the other wall-of the slot; .I therefore desire in the subjoined claims to'be-understood as claiming broadly a ribbon carrier thus constructed. In the broad aspects embodied in forms of writing machines, other than front-strike machines, employing a. ribbon carrier,

guide or vibrator andalsoin other constmctious of irontstrike machines employing a guide carrier or vibrator;

' thatjt is immaterial, whether such other machines em- .the parts are in normal position. I m

or disposed at an angle to the vertical.

ploy a ribbon carrier vertically disposed as described.

It is also immaterial so far as the main features of my invention are concerned, whether the said ribbon carrier vibrates or whether it be normally fixed against such movement, although I have shown my invention in a machine wherein said mrrier is reciprocated pr vibrated to cover and uncover the printing point ddring printing operations so as to leave the last It tter'wl-itten in sight. when Various changes may be effected without departing from the scope of my invention.
